THE TOA 900 SERIES are widely
recognized as the industry standard
in installed sound system amplification. When reliability and performance are critical – such as in
paging and music distribution for
airport, hospital, and industrial
sound systems – you can count on
the TOA 900 Series to perform
consistently, day-in and day-out.
The P-906MK2 (60 W), P-912MK2
(120 W) and P-924MK2 (240 W)
Single Channel Power Amplifiers
are engineered for high performance with wide frequency
response, very low noise and distortion, and excellent output regulation. A single module slot
allows you to easily configure
custom configurations using TOA
plug-in modules with an extensive
array of features and connector
types. Outputs include transformerisolated 25 V, 70 V and 8 ohm
plus a direct low-impedance
mode if non-transformer operation
is required.
Other features include a direct
input, selectable input sensitivity,
low-cut switch and protection
circuitry.
The 900 Series Power Amplifiers
are UL and cUL Listed and carry a
five year warranty.
Modular Single Channel Power
Amplifiers for paging, background/
foreground music distribution and
music/messaging-on-hold.
Proven TOA Quality and Reliability
Engineered for High Performance
with wide frequency response, very
low noise and distortion, and excellent output regulation.
Three Models:
P-906MK2 (60 W), P-912MK2 (120 W),
P-924MK2 (240 W)
Input Module Slot accepts most TOA
plug-in modules for custom system
configurations.
25 V, 70 V and 8 Ohm Transformer-
Isolated Speaker Outputs with screw
terminal connector and protective
cover plate.
Direct Low-Impedance Output Mode
bypasses output transformer.
Direct Input for connecting an exter-
nal mixer or other source.
Selectable Input Sensitivity to accom-
modate high or low input levels.
Master Volume Control
Low Cut Switch to limit low frequency
response.
Normal, Clip, Power, Protect, and
Signal Indicators provide unit status.
Rear Panel AC Convenience Outlet for
powering external equipment
Turn-On Delay disconnects output
during power-up.
Over-current and Thermal Protection
Circuitry prevents potential damage
from overload, short-circuit, or overheating.
